Abstract

A multi protocol adapter capable of implementing various communication modes is disclosed. The multi protocol adapter may include a plurality of communication ports to connect to a plurality of communication modules supporting different communication protocols, and a main controller to convert a signal received from one of a plurality of the communication modules and to output the converted signal to the other communication module. In this instance, each of a plurality of the communication modules is attachable and detachable, and may be connected to one of a plurality of the communication ports.

Claims

1. A multi protocol adapter comprising:

a plurality of communication ports to connect to a plurality of communication modules supporting different communication protocols; and

a main controller to convert a signal received from one of a plurality of the communication modules and to output the converted signal to the other communication module,

wherein each of a plurality of the communication modules is attachable and detachable, and is connected to one of a plurality of the communication ports.

2. The multi protocol adapter of claim 1, wherein when a first dongle comprising a first communication module of a plurality of the communication modules is connected to a first communication port of a plurality of the communication ports, the main controller recognizes the first communication port connected to the first dongle, waits for data input and output, and when the main controller receives data from a first terminal through the first communication port, processes the data based on a protocol supported by the first dongle.

3. The multi protocol adapter of claim 2, wherein while the main controller is communicating with a second terminal keeping a connection to a second dongle comprising a second communication module of a plurality of the communication modules, when a communication protocol supported by the second dongle is recognizable by the main controller, the main controller follows the communication protocol supported by the second dongle, and when a protocol supported by the second dongle is unrecognizable by the main controller, the main controller bypasses.

4. The multi protocol adapter of claim 2, wherein when the main controller transmits the received data to the second terminal through the second dongle comprising the second communication module of a plurality of the communication modules, the main controller processes data transmission according to a cycle including a state check frame for checking the communication state with the second terminal, a command frame for processing a command code for the data to be transmitted, and a completion check frame for checking the transmission completion of the data.

5. The multi protocol adapter of claim 2, wherein when the main controller transmits the received data to the second terminal through the second dongle comprising the second communication module of a plurality of the communication modules, the main controller checks the power state of the second terminal, and when the second terminal is powered off, the main controller temporarily stores the data and transmits the data to the second terminal at the time of powering on the second terminal

6. The multi protocol adapter of claim 2, wherein when a radio frequency identification (RFID) card is recognized through a RFID card reader connected to the second communication port of a plurality of the communication ports, the main controller combines information related to the RFID card with the received data, and transmits the combined data to the second terminal through the second dongle comprising the second communication module of a plurality of the communication modules.
